In this paper, we discuss a contribution toward the use of analogical reasoning by explicit system dynamics
modeling of physical processes. The relational structures found in simple models are transferred to an example of
chemical processes leading to chemical equilibrium. We present an experiment on the mutarotation of D-glucose.
A dynamical model will be built that makes use of amount of substance and chemical potential differences in
analogy to quantities of fluid and pressure differences in fluid phenomena, or electric charge and voltage in
electricity. The model is simulated and results are compared to experimental data. The approach presented is
suitable to advanced high school or to introductory college courses in applied science and engineering
